A local web-page serving tool that gives a file or directory a stable HTTPS address ending in .localhost. It can optionally take a screenshot and can stop the server when it is no longer needed.

Use it to hand someone a locally generated HTML page, preview a directory with its assets, check its status, or capture a screenshot.

It avoids manually starting a server, finding a port, and remembering to shut it down. The stable address also gives a human a simple link to open the page.

page-serve — Command for Claude Code and Cursor by yonatangross

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/yonatangross/orchestkit

Made for: Claude Code, Cursor.

Or install ork, the plugin that ships this one along with the rest of its 107 skills, 36 commands, 36 agents, 32 hooks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00111	$0.01421
Opus 5	$0.00056	$0.00711
Sonnet 5	$0.00022	$0.00284
Haiku 4.5	$0.00011	$0.00142

Security

Grade A, and why

page-serve scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

/ork:page-serve, give a human a URL

An agent that renders a page for a human needs a way to hand it over. The pattern that grew in sessions was python3 -m http.server 8991 plus portless alias <name> 8991 typed by hand: no record of the process, no stop, servers outliving the session, and one measured night (2026-09-06) where the same session did it twice and the server was still up the next morning. This skill is that pattern with a state file, a stop, a status, and a loud failure when the URL contract cannot be met.

The contract

The URL is https://<name>.localhost/<file>. No port, ever. portless's 443 service owns the port; a :1355 or :8991 in the URL is the pre-service fallback and the skill refuses rather than emit one.
One static server per name, on a free loopback port, rooted at the file's directory (so sibling assets resolve) or at the directory you pass.
State in .claude/state/page-serve/<name>.json: root, file, port, pid, url, time. status re-measures pid, route, and HTTP on every call; it never trusts the file.
Idempotent per name: same name + same root reuses the live server; a different root replaces it; --force on the alias overrides a stale route with the same name.

Usage

/ork:page-serve docs/playgrounds/roadmap-2026-09-07.html
/ork:page-serve docs/playgrounds/ --name playgrounds
/ork:page-serve <path> --screenshot          # agent-browser, returns the png path
/ork:page-serve status [--json]
/ork:page-serve stop <name>
/ork:page-serve stop --all

serve.sh prints url=, name=, port=, pid=, http=, optional screenshot=, and the exact stop= line to paste. Put the url= line in your reply's Open section.

Modes

Invocation	Script	What happens
`<path> [flags]`	`scripts/serve.sh`	prerequisites, server, alias, state, curl check, optional screenshot
`status [--json]`	`scripts/status.sh`	one line per served page: server up/dead, route registered/missing, HTTP code
`stop <name>` or `stop --all`	`scripts/stop.sh`	alias removed, server killed, state and screenshot deleted; every step reports

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
